Question

A wooden block of mass 47 g is immersed completely in a measuring cylinder containing water due to the mass of the block the water level in the cylinder rises by 20mL. what is the density of the stone?​

Answer 1

• Mass=47g
• Volume=20ml

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Density=\dfrac{47}{20}$

$\\ \sf\longmapsto Density=2.35g/ml$

SI units:-

$\boxed{\begin{array}{c|c}\sf Force &\sf Newton \\ &\\ \sf Work &\sf Joule \\&\\ \sf Acceleration &\sf ms^{-2} \\&\\ \sf Velocity &\sf ms^{-1} \\&\\ \sf Displacement &\sf metre \\&\\ \sf Pressure &\sf Nm^{-2} \\&\\ \sf Density &\sf kgm^{-3} \\&\\ \sf volume &\sf m^3 \\&\\ \sf Power &\sf Joule/second \\&\\ \sf Mass &\sf Kilogram\end{array}}$
